I don't know how many GB Destiny will be, but considering that other downloadable games on the 360 have been between 3 and 17 GB, 20 GB should work just fine.

According to the latest digital listing (via Reddit) for the game on the PlayStation Store, Destiny will swallow up 40Gbs of your PlayStation 4’s hard drive. That might not seem like too much, all considering, but it’s about 10% of the available space on a fresh console.[url=http://example.com]link[/url]

[quote]So I'm planning to preorder destiny and I was wondering how much GB is required? (including updates) Also will a 20GB hard drive go well with Destiny ONLY, or should I get more space?[/quote] Do you mean you only have 20GB of space left on your xbox's hard drive? You may have to make room on your hard drive if that's the case. The game itself won't support external memory of any kind. Your xbox hard drive has to have room for the game to run.

I would say at least 20 GB but if that's how big your hard drive is or your using a USB get a bigger hard drive as you won't be able to play

The game by itself on xbox 360 should be around 8 gb.
